{"product_id":"umi-performance-67-72-gm-a-body-factory-height-springs-rear","title":"UMI Performance 67-72 GM A-Body Factory Height Springs Rear","description":"A spring is a spring right? Wrong! When UMI  chose to manufacture our own line of springs we went all out. Designed in  conjunction with a leading Sprint Cup chassis engineer, these springs are the  best in the business. These springs are designed to add  modern handling and a crisp ride while maintaining the factory muscle car  appearance. The rear springs are wound from 9254 CrSi premium wire and feature  a linear 130 lb\/in rate. The linear rate provides consistent handling characteristics  which are important for Auto-x and Pro-Tour applications while the increase in  stiffness reduces body roll and prevents the “floating” feeling so common with  the A-body. These springs are suitable for Auto-x and Pro-Tour applications as  well as corner carving and general cruising. They have a tough, black powder  coat finish and UMI proudly manufactures these premium quality springs in the  USA.","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":53112948293943,"sku":"UMI4049R","price":189.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/4214\/2519\/files\/8415152a28ae3c7bfbf1bff1b157ce95L.jpg?v=1791391029","url":"https:\/\/burstcraftusa.com\/products\/umi-performance-67-72-gm-a-body-factory-height-springs-rear","provider":"Burst Craft","version":"1.0","type":"link"}
